Objective

The objective of the proposed project is to study the seismic response of rigid connections between precast columns and footings, two-way hinge connections between precast columns and footings, and precast column to pile shaft connections.  The data will be compared with the performance of the columns with that of similar cast-in-place construction and any necessary refinements will be identified based on the data and analyses.  The ultimate objective is to make recommendations to Caltrans regarding precast column connection details and their design.
